Your first name of Knaack makes you quick-minded, versatile, and very expressive. This name has given you an interest in people and a desire for new experiences. It spoils patience and weakens your stand in matters of principle. Because you are so expressive, you could excel in sales but, here again, must avoid talking the customer both into and out of the sale. The qualities in this name tend to narrow your opportunities by making it difficult for you to concentrate. You make the effort to communicate with others because you place importance on having people like you. The use of this name creates a lack of stability in your affairs as it inclines you to procrastinate. When you are annoyed or under excessive pressure, be careful not to be biting in your speech, or fault-finding and hard to please. You could suffer bitter experiences through attracting wrong types of association and can be drawn into circumstances involving you in unwise situations. It could also cause upsets in the fluid functions: in the kidneys, bladder, or circulatory system of your body.
